westhemann Posted October 13, 2003 Report Share Posted October 13, 2003 hey i was thinking today and i think it would be a simple process for me to build a benchtop disc sander large enough to sand a complete guitar body..i think about a 48" diameter would be cool,but a 30" would probably suffice. but where would you get the sandpaper to glue to it?

feylya Posted October 14, 2003 Report Share Posted October 14, 2003 Maybe stick a few sheets together? Make sure they don't overlap but I'm sure there's some arrangement that would allow for even sanding. Quote Link to comment Share on other sites More sharing options...
Setch Posted October 14, 2003 Report Share Posted October 14, 2003 Problem is speed - if you've used a disc sander you'll have noticed that the edges cut much faster than the center - they travel faster. A bigger disc would make this exponentially worse - a guitar sized sanding disc would cut faster at the edges, and tend to round the surface of the guitar. Also, a disc with that much surface area would be very easy to stall - unless you beefed up the motor, which would leave you with a new problem of how to hold onto the guitar! In all my time looking at guitar building and woodwork sites, I've never seen a super-sized sanding disc, and I'm sure there is a reason - IMO you'd do much better to invest your time in making a drum sander.

Brian Posted October 14, 2003 Report Share Posted October 14, 2003 I know they make 8" and 12" belt sanders for the glass industry to bevel the edge's. They are variable speed as well. Quote Link to comment Share on other sites More sharing options...

westhemann Posted October 14, 2003 Author Report Share Posted October 14, 2003 yeah canuck,that's what i am talking about. i figured about a 3 hp electric motor the reason i want it so large is so that i could put the support table up a little more than halfway so you wouldn't get the grabbing effect you get around the center Quote Link to comment Share on other sites More sharing options...
Setch Posted October 14, 2003 Report Share Posted October 14, 2003 Ok, I assumed you meant to sand the whole face or back of the guitar. However, I don't see the advantages of a bigger sander if it's just for sanding the edges of the body - Most guitars are curved, so you rarely need to sand large flat areas on the sides. On the rare occasions that you do, a belt sander is much better suited since it sands with the grain, and doesn't create crossgrain scratches. As far as I can see the only real difference with a mega-sized sanding disc is you need bigger bits of sandpaper, and it takes up more room! Eitherway, I'd be interested to hear if it works out...
